ngx_posted_accept_events queue can be processed first. After processing, the ngx_accept_mutex lock will be released, and then the time in the ngx_posted_events, this greatly reduces the time occupied by the ngx_accept_mutex lock. Server Load balancer When establishing a connection, when multiple sub-processes compete for a new connection time, only one worker sub-process will eventually connect the resume,

Article Title: about dual-connection server load balancer. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Save everyone's time. First, let's talk about the theme: 　　 Packet-level TCP/UDP load balancing and NAT (Network Addres

Demonstration Fault Background:In the network environment as shown in Figure 14.20, engineers have completed the startup of the dynamic routing protocol for all router interface addresses in the environment. Currently, the neighbor relationship of each VPN Router is normal, and route learning is normal, to make full use of the non-equivalent Server Load balancer feature, engineers need to generate two rou

This article mainly introduced the Nginx to do nodejs application load Balancer Configuration example, this article directly gives the configuration instance, needs the friend can refer to.load Balancing allows the user's requests to be distributed across multiple servers for processing, enabling access to a huge number of users. Load-balanced Architecture:For co

Apache HTTP Server is selected as the front-end Server Load balancer, and two Tomcat clusters are selected at the backend. The selected configuration method is session sticky (sticky session ), this method forwards requests from the same user to a specific Tomcat server to avoid session replication in the cluster. The disadvantage is that the user only communicates with one server, if the server is down, it

This article describes how to configure Simple Server Load balancer on Docker. The host machine is Ubuntu14.04.2LTS, two CentOS containers, Nginx for the host machine, and tomcat 7 for the two containers. The architecture is as follows: the principle of this solution is to map the host machine port and the docker container port (that is, a port accessing the host machine will be mapped to the corresponding

Since the release of this series, I have received replies from many friends! Thank you very much. At the same time, many friends have asked some questions, some of which are basic questions. Due to the time, they will not reply to them one by one. If they do not understand, I hope you will learn by yourself! Although this series is not difficult, many of the knowledge is required by default, such as the concept, principle, and Web farm of Server Load

, there are also real-time static content, the Mop-like hodgedge and Netease community use such strategies.Category 3: The content changes in real time and is very personalized. For example, for mailbox applications, the content provided by such services cannot be static and can only be optimized through regional deployment and load balancing.For the vendors that provide cdn services, static content cdn is naturally no problem.
